Brake noise, especially brake squeal, has been a subject of intensive research both in industry and academia for several decades. Nevertheless, the state art simulations does not provide predictive tool, extensive experimental investigations are still necessary to find an appropriate design. Actual focus on consideration nonlinearities which fact essential this phenomenon. Unfortunately, by far...

In winter, some freight trains with composite brake blocks experience unexpected long braking distances, which seriously jeopardizes running safety. The reasons for the distances are still not completely understood, and therefore it is difficult to suggest preventive measures. Up now, has really been studied how a layer of ice that often found between block wheel influences process. To investig...

A room-temperature light-driven molecular brake (1), consisting of a pentiptycene rotator, a 3,5-dinitrophenyl brake, and a photoisomerizable ethenyl spacer, is reported. The rotation rates of the rotator differ by about 9 orders of magnitude between the brake-on (cis-1) and brake-off (trans-1) states.

The prediction capability of the brake system vibration is still unable to cover a broad range of frequencies. Current predictive models are contained within a particular range to cater for specific vibration types. Therefore, a numerical model which could make predictions in a broad spectrum range is required. The model presented in this paper is derived with such aim. The model is derived fro...

This paper investigates an original aspect in the study of longitudinal dynamics of trains submitted to braking actions: the influence of application time admitted ranges on in-train forces. Basic theoretical aspects are outlined and experiments were carried out in order to accurately determine the filling characteristics of brake cylinders. These were implemented in an original simulation prog...

The purpose of this paper focuses on designing an intelligent, compact, reliable, and robust auxiliary vacuum brake system (VBS) with Kalman filter and self-diagnosis scheme. All of the circuit elements in the designed system are integrated into one programmable system-on-chip (PSoC) with entire computational algorithms implemented by software. In this system, three main goals are achieved: (a)...

This paper deals with analysis of the influence fuel injection pressure ternary (diesel + Mahua methyl ester Pentanol) on emission, combustion and performance characteristics a four stroke, single cylinder, common rail direct diesel engine working at constant speed varying operating scenarios. The usage raised NOx emission (12.46 %) value specific consumption (SFC) decrease in BTE (brake therma...

In this study, the effect of tire inflation pressure on vehicle during braking was investigated experimentally. The experimental study carried out in Brake-Suspension Test Device designed as a half-vehicle model, which enables brake tests to be performed laboratory. During tests, total nine different pressures from 26 psi 40 standard value were taken into consideration. As result experiments se...

This paper describes our first step for advances in humanmachine interactive systems for in-vehicle environments of the UTDrive project. UTDrive is part of an on-going international collaboration to collect and research rich multi-modal data recorded for modeling behavior while the driver is interacting with speech-activated systems or performing other secondary tasks. A simultaneous second goa...
